Title: Process and apparatus for the chemical conversion of a starting material with integrated low-temperature fractionation of air
Inventor: PIEHLER SIEGFRIED E DIPL ING
IPC: F25J3/04
Filed: 1993-08-13
Abstract: The process and the apparatus serve for the chemical conversion of a starting material and simultaneous production of oxygen and/or hydrogen by low-temperature fractionation of air. Feed air is compressed, purified, cooled and fed to a rectifying system having at least one rectifying column. At least one product stream from the rectifying system is fed to the chemical conversion. Exhaust gases from the chemical conversion are expanded to produce work in a gas turbine and the energy obtained therefrom is used at least in part for the compression of feed air. Mass transfer is effected by a packing in at least one section of the rectifying column or of one rectifying column of the rectifying system.
Patent DE-4327433-A1 (DE)
Title: Sensor-based hit (strike) surface for sport
Inventor: NAUL ROLAND PROF DR PHIL
IPC: A63B43/00
Filed: 1993-08-14
Abstract: In an arrangement for registering hits (strikes) during sporting activities, having a hit surface which has contact-sensitive sensors, the invention proposes a playing ball with an electrically conductive surface and sensors on the hit surface which are connected to two different electric terminals and are arranged alternately and at a distance from each other. In this way it is achieved that not every pressure loading of the hit surface leads to the indication of a hit, but that only contacts of the hit surface by the playing ball lead to an indicated hit. The arrangement according to the invention can therefore also be used in the case of sports in which teams act in the immediate vicinity of the hit surfaces.

Title: Method for transmitting digitised television and/or sound radio signals
Inventor: KLANK OTTO DIPL ING
IPC: H04L27/26
Filed: 1993-09-10
Abstract: A method of this type operates with a distribution of the signal streams among a multiplicity of carriers and correspondingly increased symbol length and a synchronisation symbol spread over all carriers. The method is also referred to as OFDM (Orthogonal Frequency Division Multiplex). The object is to develop this method in such a way that only one symbol is required overall for synchronisation and thus more channel capacity is available to transmit the useful information or the error precoding. According to the invention, the power of the signal is zero during part of the synchronisation symbol period. Over a further time segment, a modulation method is used in which only every second carrier is used with half of the actual symbol length. In the signal part of the synchronisation symbol, bit information with optimum autocorrelation characteristics is transmitted, the information sequence of the bit information being allocated to the carriers in succession from the lowest to the highest frequency. In the receiver, rough synchronisation is carried out on the basis of the zero-power sub-symbol, followed by the evaluation of the received signal part of the synchronisation symbol and then a more accurate definition of the time domain. In particular for HDTV transmission or audio transmission. <IMAGE>
Patent DE-4330949-A1 (DE)
Title: Process for producing zeolite high-temperature molecular sieve membranes having separating and reactive properties
Inventor: KOELSCH PETER DR
IPC: B01J20/18
Filed: 1993-09-08
Abstract: The invention relates to a process for producing membranes which comprise zeolite molecular sieve crystals in a metal layer. The zeolite-metal composite can be used as a free foil, but also fixed to a porous support. Such membranes enable the separation of fluid mixtures by diffusion, permeation or pervaporation. Since the membrane also has a high thermal stability and chemical resistance, it can be used at high temperatures as a reactive catalyst membrane. Areas of application are selective mass-separation processes for gaseous (permeation) and liquid (pervaporation) mixtures. At elevated temperature, depending on the catalytic properties of the zeolite molecular sieve crystals included, shape-selective catalytic reactions proceed. Furthermore, the membranes can be used in chemical sensors, in which case only certain components of a product mixture can pass to the detector. The development of novel high-temperature membranes based on zeolite molecular sieves in a metal matrix is also intended to open up novel development possibilities in reaction technology and environmental technology in competition with thermal separation methods.

Title: Substitution of defective reactor units in a continuous chemical process - comprising transferring energy between the out-going and new reactor units, e.g. in high temp. catalytic hydrogen prodn.
Inventor: NAMBA SHIGEAKI
IPC: B01J19/00
Filed: 1993-10-26
Abstract: Process for exchanging a reactor (10A) in a chemical plant, whose operational temp differs from its non-operational temp, is novel in that energy from a previously operational reactor (10A) is transferred to a new chemical reactor (10B) and the former reactor (10A) is substituted by the new chemical reactor.

Title: Overvoltage protective circuit for mos components
Inventor: TERLETZKI HARTMUD
IPC: H01L27/02
Filed: 1990-03-22
Abstract: The invention relates to an input protective circuit for MOS components which contains a resistor R, a thin oxide transistor DOX and a punch-through component. The use of the punch-through component instead of a field oxide transistor in the protective circuit reduces the breadkown rate of integrated circuits through ESD discharges. The problem of the delayed response of a protective circuit and the concomitant interference through voltage damage are thus minimized. The advantage of the protective circuit of the invention over prior art types lies in that it becomes active immediately on reaching the punch-through voltage and thus responds immediately.

Patent WO-9700412-A1 (WO)
Inventor: BRUNNER REINHARD
IPC: F26B7/00
Filed: 1996-06-10
Abstract: The invention concerns a method and device for drying sawn timber (5) stacked on spacing battens, or other hygroscopic panel- or stick-shaped articles, at reduced pressure in a vacuum-tight drying chamber (9) provided with fans (13) which act in a direction at right angles to the chamber's longitudinal axis and circulate a gaseous drying medium, with one or more heat registers (14) arranged along the length of the drying chamber, and with a dehumidifying system (12) (condenser) inside or outside the drying chamber. The purpose of the invention is to allow regulation of the heat supplied to particular stack regions (A, B, C, D, E) and thereby control the moisture loss per unit of time from the timber in those regions independently of other stack regions of the same drying batch in the same drying chamber, thus eliminating dispersions of timber moisture caused by local drying conditions in the drying chamber associated with different chamber-specific and external factors. The aim is to eliminate differences in timber moisture in the various stack regions even during the drying phase and before the final conditioning phase, and as far as possible to prevent the occurrence of further differences in timber moisture caused by uneven heat loss to the outer chamber walls or by uneven heat supply.
